Answer:
This would be Helium(He)
Step-by-step explanation:
Its Helium because the bohr model in the picture has 2 electrons.
On the periodic table, it says that Helium has 2 protons which are also equal to electrons
Answer:
The mean birth weight for the sampling distribution is
3,500 grams.
Step-by-step explanation:
The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population. If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean. This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.
Answer:
A
Step-by-step explanation:
The average rate of change is the change in attendance over change in time.
Δy / Δx
(333.7 - 298.3) / (5 - 2)
11.8
So the average rate of change is an increase of 11.8 thousand people per year.
Answer:
The mixture that is an equivalent ratio is:
1.5 white 2 blue
Step-by-step explanation:
a) Data and Calculations:
Mixtures of the same color because they are in equivalent ratios:
3 cups of white and 4 cups of blue: equivalent ratio = 0.75: 1 (75%) since 3/4 = 75%
6 cups of white and 8 cups of blue. equivalent ratio = 0.75: 1 (75%) since 6/8 = 75%
Other mixtures:
5 cups white 6 blue: equivalent ratio = 0.83: 1 (83%) since 5/6 = 83%
1 white 1 1/2 blue: equivalent ratio = 0.67: 1 (67%) since 1/1.5 = 67%
4 white 3 blue: equivalent ratio = 1: 75 (1.33%) since 4/3 = 1.33%
1.5 white 2 blue: equivalent ratio = 0.75: 1 (75%) since 1.5/2 = 75%
Therefore, the mixture with equivalent ratio as the initial mixtures is 1.5 while 2 blue.
